What happens when you send a request out to the world to chronicle, via video, a single day on Earth? You get 80,000 submissions and 4,500 hours of footage from 192 countries. Producer Ridley Scott and Oscar-winning director Kevin Macdonald took this raw material -- all shot on July 24, 2010 -- and created Life in a Day, a groundbreaking, feature-length documentary that portrays this kaleidoscope of images we call life. National Geographic is bringing it to theaters starting in July. Prepare to be amazed!

There are dull spots, as with any other day, yet "Life" aims to be, and occasionally is, like a YouTube-y "Our Town," giving a sense of what it is to be alive on planet Earth.

Despite having no conventional narrative, other than the sleeping, waking, rising, bathing, eating and living cycles of ordinary people across the globe, "Life in a Day" is, without exaggeration, a profound achievement.
